Yes. I think it is.

I remember several other, mostly smaller specimens nearby. They could have been associated with Oregon White oak. A large example of that species (4 feet diameter, 150 feet tall) was nearby. While the example here was fairly large (4 inches across the cap = 10cm) many of the others were mere buttons.

Another thing: this is the only Bolete I’ve been able to grow. Suillus caerulescens is more common in my area, but doesn’t respond to my cultivation technique. The dark ruby color in the stipe is suggestive.

and it’s so close to my obs. http://mushroomobserver.org/149291?q=1a6Sy

What bothers me is that this specie is a North American sp. What do you think?
